S52 finally!

[parkerbink]

Almost.

[Panici]

Love that steering wheel!
What's the outside diameter on that?

Still has the single-stage airbag?

[parkerbink]

Thanks, not sure. I'll measure it. Yes single stage bag that plugged right in, third wheel was the charm. I got in on the Z3 FB group from a guy that got it from England & totaled his car before it came.

[Panici]

Would appreciate a measurement, thank you!

It'd be a big visual improvement over the giant airbag wheel in my E36 M3 (on which the leather is torn).
Just don't want to go up in diameter.

[parkerbink]

15.2" = 386.08mm.

It does not feel that big.

[parkerbink]

Done, very happy.

I uploaded a quick video.

Boost!

[parkerbink]

This happened today.

I'm blowing oil from the bottom of the dipstick tube & it's hitting the cat & looked like burning oil, scared me before I verified that was what is happening.

[parkerbink]

Thanks to finally having boost, my 27 year old dipstick tube O ring failed & blew oil onto the cat scaring the crap out of me with billowing blue smoke. I cleaned it up & replaced the O ring.

So far so good.

[parkerbink]

Looks like I blew a cylinder.

Did a compression test and am 10 to 15 lbs lower than before the SC ( was 188-195) on the still good cylinders (175-185) but have 125 on 3. Oil on top of most pistons 3 is the worst.

[parkerbink]

Another oddity, no blue smoke until temp is at 1/4.

Here are the plugs. (in for under 300 miles).

[Panici]

What are you doing for crankcase ventilation?

Surprised to see an engine failure at such low boost. What kind of engine management / tune are you running?

[parkerbink]

I replaced the "PVC" when I put in the M50 manifold, the SC has it blocked at it's inlet so I think is bypassed. The output that went to it is now running to the intake tube.

The bronze is the plug the blue hose used to connect to, the small hose on teh intake is where the blue hose is going & it has a valve inline

[parkerbink]

The plot thickens (he said seemingly to himself)

It was suggested I do another compression test with all plugs out. Here's what I have: Also, the smoke is worse.

[moatilliatta]

Can you put PCV into the intake? (VENT)

Does the supercharger have a restrictor or need one for the oil supply?

If your cylinders are misfiring and have fuel in them the comp test numbers will be low.
